Widgets-Wont Save Changes

Hello,

I am using WordPress version 2.1.1, and the latest version of the widgets plugin. I’m pretty sure I installed it correctly, it worked fine for about a week. Now all of a sudden it won’t save changes I make to the widgets. When I make my changes and click the “save changes” button a blank page appears and no changes occur on my blog. I’ve searched the forums but nothing seems to have worked. Any suggestion is much appreciated.

Thanks in advance.
